changed in accordance with different waterpressures prevailing 'indifferent localities and is proof against tampering or accidental ydisarrangement.

\ Further objects of the inventionwill hereinafter appear and be definedin the claims. The invention has been clearly illustrated s in theaccompanying drawing which represents in vert-ical cross-section acellar-drainwell equipped with my improved, .device which is primarilyintended for discharging the drainage 'of cellars or sub-basements thefloors of which are below the levelof the sewers,.so that consequentlyforce must be applied to extract the cellar-water, in contradistinctionto systems in the water drains gravitatively.

. In the drawingthe well or basin W is sunk below the floor of thecellar which is to be drained, and a high-pressure water service-pipe Penters the well and has at its lower end a strained-casing S connectedwith a valve casing 10 provided with a seat 11 the aperture of which isadapted to be opened or closed by a superposed valvedisk 12. Theorganization of the valve is such that the water pressure tends to closethe valve-disk, and the latter has a stem 13 guided in a packed sleeve14 which is removable from the casing so that a smaller or larger stemmay be substituted for the one in use, according to the effectivetoppressure which it is desiredto obtain against y the upper area of thedisk 12. An ear 15 on E lated to a lever 17 pivoted to the valve stem Beit known that I, ALEXIS R. PRiBIL, af

cit-izenof the United States of America, residing at Detroit, in thecounty' of Wayne and State o1c Michigan, have invented cer-l tain newand useful Improvements i'n Automatic C'ellar-Drainers, o-which theollowing is a specification, rererencebeing had and having its free endconnected (by links 18) wit-h a float 19 which is guided for freevertical movement on a pipe 20. This pipe constitutes a 'suction pipewhich has a strainer 21 at its lower .end and vthrough which thewellwater may be drawn .upward by a streamissuing throughy anejectornozzle 22when the valve disk 12 is opened. This invention relatesto automatic drain l In the preferred construction sho-wn, theejector-nozzle is screwed into a casing 23 having its discharge-endconnected with a waste pipe 24, which leads to a sewer or otherconvenient discharge-conduit.

The operation is 'as follows: As the Water rises in the well, it willhave a tendency The invention has, furthermore, for itsf object theprovision of an improved fluid' controlling device which may be variedor" normally to raise the float at the level shown. However, inasmuch ashigh-pressure water is holding the valve disk closed, the float. cannotat first rise with the well water until the latter has att'ained a levelsubstantiallyV quickly throw the valve wide open thereby allowing a fullstream of high pressure water to pass through the Iejector nozzle andthus begin to draw-up the well water through the `suction pipe anddischarge the same through the discharge pipe. As the well-water levelfalls, so will the float descend until the high pressure again becomeseffective on the top-surface of the valve disk and quickly close thesame.-

As'will be readily understood, the location of the float 19 on the pipe20 below the plane of theinjector nozzle`22, causes the inlet end of`the discharge element (the pipe 20, casing 23, and pipe 24vconstituting such element) to act as a guide for the movements of thefloat to prevent placing any lateral strains on the valve or its stem;furthermore, this particular location of the loat enables the device t0be installed in a well of comparatively small area in horizontalsection, the well being of a size sufficient to receive the necessaryparts in compact form and at the same time permit of the use of a floatof considerable size. It should also be noted that substantially all ofthe operating parts (excepting the' iioat itself) are posi.- tionedentirely above the Water level so that rusting, etc., of these parts ispractically eliminated, since no actual contact of drainage iuid andparts is had.

Any leakage around the valve disk and its seat., as Well as at the otherconnections Will gravitate in the Well and form a part of the liquid .tobe automatically ejected therefrom by the operation of the ioat.

I claim l l. In a device of the character described and in combination,a fluid-pressure supply, a Waste de'scharge element having a permanentlyopen inlet, injecting means adapted to be operated bysuch supply andextending into said discharge element above its inlet end, and meansfoi` controlling the passage of the supply to the inject-ing means, Saidcontrolling means including a lioat carried by and movablelongitudinally of said element below the plane of the injecting means,said element acting as a guide for the float.

2. In a device of the character described and in combination', a Wastedischarge ele- A ment having its inlet end adapted to extend into acollecting basin, said element including a pipe leadmg upwardly from theinlet end,` Waste iuid ejecting mechanism, and means for controllingsaid' mechanism, said means including a float movable longitudinally o-fand guided by said pipe, said mechanism beinv operative in said elementabove the float, the movements of the float controlling the operation ofthe mechanism.

3. In a device of the character described and in combination, afluid-pressure supply, a Waste discharge element, an injector nozzleext-ending into the discharge element at a point above and removed fromits inlet end, a valve between said supply and nozzle, a float movablelongitudinally of and guided by said element below the plane of thenozzle, and connections between said float and the valve to cause theupward movement of the float to open the valve When the flotationpressure reaches the pressure of the supply on the valve.

In testimony whereof I aix my signature in presence of two Witnesses.
